‘Relationship breakdown is the largest single trigger of rough sleeping, leading to 42% of male rough sleeping’.

This is according to the February 2018 briefing paper (pdf) from the House of Commons Library. This paper provides background information on the problem of rough sleeping in England, and outlines Government policy on this issue.

The paper finds:

The most recent statistics published on 25 January 2018 recorded a 169% increase in the number of people sleeping rough in England since 2010
Among women, 35% slept rough after leaving home to escape domestic violence

Despite allegations of serious abuse in immigration detention centers, the UK
persisted in not imposing a maximum time limit for immigration detention, and
continued to detain asylum-seeking and migrant children.

This is from the January 2018 report (pdf) from the Human Rights Watch (HRW). World Report 2018 is their 28th annual review of human rights
practices around the globe.

The report summarises key human rights issues in more than 90 countries and territories worldwide, drawing on events from late 2016 through November 2017.

The report finds:

Germany over the past year made headlines when the Alternative for Germany (AfD) became the first far-right party to enter its parliament in decades
Despite a strong tradition of protecting civil and political rights, Australia has serious unresolved human rights problems. Australia continued in 2017 to hold asylum seekers who arrived by boat on Manus Island in Papua New Guinea and on the island nation of Nauru, where conditions are abysmal
Bahrain’s human rights situation continued to worsen in 2017. Authorities shut down the country’s only independent newspaper and the leading secular-left opposition political society.
In Bangladesh, civil society groups faced pressure from both state and non-state actors, including death threats and attacks from extremist groups.
